Purpose The purpose of this study is to design a zero-energy home, which is known to be capable of balancing its own energy production and consumption close to zero. Development of low-energy homes and zero-net energy houses (ZEHs) is vital to move toward energy efficiency and sustainability in the built environment. To achieve zero or low energy targets in homes, it is essential to use the design process that minimizes the need for active mechanical systems. Design/methodology/approach The methodology discussed in this paper consists of an interfacing building information modeling (BIM) tool and a simulation software to determine the potential influence of phase change materials on designing zero-net energy homes. Findings BIM plays a key role in advancing methods for architects and designers to communicate through a common software platform, analyze energy performance through all stages of the design and construction process and make decisions for improving energy efficiency in the built environment. Originality/value This paper reviews the literature relevant to the role of BIM in helping energy simulation for the performance of residential homes to more advanced levels and in modeling the integrated design process of ZEHs.

Purpose The purpose of this paper is to improve the understanding of the impact of mass timber construction methods on construction performance through the successful delivery of the first-of-a-kind tall wood building, Brock Commons Tallwood House (Tallwood House). This paper is one of a set of papers examining the project; companion papers describe innovations used during the mass timber design and construction processes. Design/methodology/approach A mixed-method, longitudinal case study approach was used in this research project to investigate and document the Tallwood House project. Quantitative data were collected to perform the following analysis: hook time, the variability of productivity and schedule reliability. Members of the research team observed construction progress, meetings and decision-making, conducted periodic interviews and reviewed project artifacts. Findings The research presented in this paper is the culmination of a longitudinal study aimed at studying the innovation process on a project where radical innovations of structural systems were developed. Prefabrication, combined with the use of a virtual design and construction (VDC) model for planning and fabrication and early collaboration with trades, construction managers and consultants, increased the labor productivity of the on-site erection of the mass timber structural components and envelope panels and expedited the construction schedule. Originality/value This paper details an in-depth investigation into the construction productivity for a unique building project and lessons learned. The case study chosen is the construction of Tallwood House at the University of British Columbia. Tallwood House was the tallest mass-timber hybrid building in the world at the time of its construction.

Purpose The dynamic nature and complexity of construction projects make it challenging to ensure that the engineer-to-order (ETO) materials supplied onsite match changing needs. The quick and efficient communication of required changes in material fabrication, delivery and use, due to changes in the design and construction schedules, is needed to address the challenges. This study aims to provide a novel integrated management framework with its embedded informatics to help major stakeholders efficiently absorb agility during communication to deal with required changes and improve workflows. Design/methodology/approach An integrated management framework is developed that integrates the milestones in look-ahead plans and structured iterative processes for major supply chain stakeholders to quickly disseminate information emanating from changes in design, schedules, production and transportation. A prototype system is devised including the informatics to support the framework, which consists of BIM-RFID functional modules and a central database and uses a client-server architecture. The usefulness of the prototype is illustrated using a construction of part of a fictive but realistic high-rise building. Findings The integrated management framework with the informatics provides major stakeholders with the ability to coordinate their activities efficiently and stimulate their agility (measured by process time) in planning and controlling material information. Although only a fictive example was used, it is shown that the use of the system is likely to result in a substantial reduction in the time required to deal with required changes when delivering ETO materials onsite (by 18% in the example). Research limitations/implications The functionalities of the prototype system can be easily scaled up to coordinate changes in the design and scheduling of other types of materials. More functional developments are needed to show the extent of the possible improvement for entire construction projects. Future work should focus on investigating the possible improvements for other types and sizes of construction projects, and eventually in real-world construction projects. Practical implications By fitting the look-ahead plans into structured iterative processes through digital data sharing, stakeholders increased their capability to quickly capture required change information and resolve associated problems. This is particularly useful for the management of ETO supply chain processes, where prefabricated elements such as ductwork, plumbing, and mechanical systems typically have to be modified because of last-minute design and schedule changes. Originality/value Unlike traditional information technology (IT) based supply chain management practices, this research is characterized by a process-centered management framework that provides explicit decision points over iterative planning processes for major stakeholders to manage material information.

The first step toward developing an automated construction workers performance monitoring system is to initially establish a complete and competent activity recognition solution, which is still lacking. This study aims to propose a novel approach of using labor physiological data collected through wearable sensors as means of remote and automatic activity recognition.,A pilot study is conducted against three pre-fabrication stone construction workers throughout three full working shifts to test the ability of automatically recognizing the type of activities they perform in-site through their lively measured physiological signals (i.e. blood volume pulse, respiration rate, heart rate, galvanic skin response and skin temperature). The physiological data are broadcasted from wearable sensors to a tablet application developed for this particular purpose, and are therefore used to train and assess the performance of various machine-learning classifiers.,A promising result of up to 88% accuracy level for activity recognition was achieved by using an artificial neural network classifier. Nonetheless, special care needs to be taken for some activities that evoke similar physiological patterns. It is expected that blending this method with other currently developed camera-based or kinetic-based methods would yield higher activity recognition accuracy levels.,The proposed method complements previously proposed labor tracking methods that focused on monitoring labor trajectories and postures, by using additional rich source of information from labors physiology, for real-time and remote activity recognition. Ultimately, this paves for an automated and comprehensive solution with which construction managers could monitor, control and collect rich real-time data about workers performance remotely.

Purpose - This article explores the ways innovation becomes enabled through knowledge management and sharing which has important implications for establishing and sustaining the culture of innovative thinking in project-based construction firms. We adopt reflective practitioner perspective in order to explore this relationship. Design/methodology/approach - Thirty semi-structured interviews were conducted with the construction sector professionals whose rules are most relevant in the connection between innovation and knowledge management. Thematic analysis and cognitive mapping technique were used to analyse the interview data. Findings - The research findings indicate that due to the complexity of project-based construction firms a more holistic approach to knowledge management and organisational learning at the firm level is required. This would enable a culture of continuous and coordinated knowledge flow that facilitates innovation and continuous improvement in project-based firms. Practical implications - This article has important implications for practising managers in project-based construction firms. By better understanding the ways organisational knowledge can be managed to become an enabler of innovation would allow to build and enhance firms’ innovative capabilities, individual and team competencies. There is a real need for innovation knowledge managers as formal job positions in the construction sector. Originality/value - This article contributes to construction innovation and project management research and practice by providing insights into establishing and sustaining the culture of learning and innovative thinking.

Purpose: Critics of claims about BIM’s capability to revolutionise construction industry practices, describe it as overhyped, fallacious, and therefore suggest that there is need for a more critical examination of its’ change impacts. Others have posited that the changes BIM induces are evolutionary rather than revolutionary. In this vein, a careful analysis of the nature of such changes was undertaken to distil actual changes that happened, and the type of agency that brings such changes about. Design: Drawing from appropriate qualitative research strategies, data was collected through key informant interviews from consulting organisations in South Africa that have implemented BIM within their organisations and on projects. Findings: Changes in organisations’ work practices were evident in their workflows, formal/informal methods of interaction, norms, leadership and authority structures, remuneration, and the way work was conceived or conceptualised. Furthermore, changes in organisational work practices do not solely occur through the direct agency of the BIM tool’s implementation. Instead, BIM-induced change occurs by delegated, conditional and needs-based agency – which are not mutually exclusive. Originality: The nature of changes in professional work practices could be misconstrued as being solely due to the actions of agents who actively participate in implementing BIM. The discussion in the literature has been advanced from general to specific theoretical understandings of BIM-induced change, that emphasise the need for construction stakeholders to actively participate in developing the innovations that drive change in the industry rather than hand the power to drive change to BIM authoring and management application developers who have less stake in the industry.

Purpose This study aims to examine relationships between several key technology acceptance variables that predict workers’ wearable sensing devices (WSDs) acceptance in the construction industry by using technology acceptance model, theory of planned behavior and unified theory of acceptance and use of technology (UTAUT) model. The study proposes a hybrid conceptual model to measure construction field workers’ intentions to use WSDs and their usage behaviors. The study introduces variables that are instrumental in understanding and improving WSD acceptance in construction. Design/methodology/approach The study was carried out using a structured literature review, online survey and structural equation modeling. A total of 195 field workers across the USA, with experience in using WSDs, participated in the study. Findings Results indicate that all three theories predict WSD acceptance with variables explaining at least 89% of the variance in actual use, with the UTAUT outperforming other models (91%). However, the differences between the predictive power of these models were not statistically significant. A hybrid conceptual model is proposed using findings from the present study. Practical implications The study contributes to knowledge and practice by highlighting key variables that influence WSD acceptance. Findings from this study should provide stakeholders with critical insights needed to successfully drive WSD acceptance in the construction industry. Originality/value To the best of the authors’ knowledge, this is the first study that evaluates the predictive strength of multiple technology acceptance theories and models within the construction worker safety technology domain. Additionally, the study proposes a hybrid conceptual model which could provide practitioners and researchers with information pertinent to enhancing WSD acceptance.

Purpose This paper could be considered as the first step of grounding the ambitions and speculations about hyper urban planning. In other words, it is just a brief approach for the critical discussion of hyper urban planning field, without too many details or long explanations, so further studying, arguing and additional future research should be done. Design/methodology/approach The scientific methodology is based on descriptive and analytical methods, in addition to case study method of data collection. Therefore, the paper has reviewed 16 case studies, which could arguably be lumped under the title of “hyper urban planning.” Findings The study focuses on proposing a new way to view urban planning, that is the hyper urban planning, which could be considered as a sort of specialized urban branch of advanced level, characterized by special criteria, which stimulates innovative and creative proposals for the future smart cities. Research limitations/implications Hyper urban planning field generally aims to contribute to liberating and releasing the full creative imagination of the urban planners’ minds, outside the box and away from the exaggerated strict constraints. Practical implications The study has been based on theoretical aspects in addition to empirical experiments. The practical aspects reflect the potential and promising features of hyper urban planning, especially with regard to using creativity, sustainability and innovative technology solutions. Social implications The paper’s analyses show that many hyper urban proposals have a high potential sustainability, environmentally, socially and economically. Originality/value As urban problems and built environment challenges have become more complex, the proposed vertical eco-cities under the umbrella of hyper urban planning field may arguably be promising and more sustainable urban solutions for the previously mentioned challenges.

Purpose The construction industry is currently responding to pressures of industrialisation happening across all sectors. Consequently, offsite construction (OSC) has become a vehicle to achieve industrialisation. This requires changes in traditional construction processes resulting in possible changes in construction skill requirements. Accordingly, the purpose of this study is to identify and review prevailing OSC practices and skills in the Australian construction industry. This study aims to critically analyse the existing skill profile classifications through a single case study and identify the need for an OSC specific skill classification. Design/methodology/approach This study follows a case study design, with an in-depth analysis of a single construction project. Only one case study was studied because scientifically, one example was enough to prove that the prevailing skill classifications do not represent OSC skills in a modern context. Data was retrospectively collected through semi-structured interviews of project stakeholders representing design, manufacture and assembly. Content analysis was conducted to analyse the collected data and produce findings. Findings This study identifies the inadequacy of the existing classification system, unavailability and the need of OSC specific skill categorisation. It highlights new skills that enter OSC; building information modelling engineer, three-dimensional draftsperson, OSC project manager and project coordinator, which are not identified in the available Australian skill classifications. These, together with existing skills need to be carved in to create a new skill classification. Originality/value This study is the first of its kind where a comprehensive OSC project is evaluated as a case study to determine OSC skill classification requirements in Australia.
